Circular tube settler module



FIG. 1 is a perspective view of a circular tube settler module showing my new design;

FIG. 2 is a top plan view thereof; and,

FIG. 3 is a front elevation thereof.

The bottom plan view is essentially identical to the top plan view and both side elevations along with the rear elevation are essentially identical to the front elevation. 

The ornamental design for a circular tube settler module, as shown.
